jQuery has a nice efficient event delegation mechanism, that lets you listen for events on elements that don't even exist yet, by specifying selector patterns and listening on the root element with a few global event handlers, instead of adding listeners to every leaf element as it's created. It does all the bookkeeping and event handling in one place, so it saves a lot of memory and time. So not only does it work consistently across all browsers, but it also doesn't suck!
